IMPROVEMENT IN PAPER BAG-S.

Specification forming part of -Letters Patent No. 105,87 7, dated August2, 1870.

To all whom it may concern:

Chagrin Falls, in the county of Cuyahoga and State of Ohio, haveinvented certain Improvements in Paper Bags, of which the following is aspecification: y

The object of this invention is to produce a satchel-bottom paper bag,the bottom oi which shall be readily folded into the most desirableform, securing greater facility and therefore greater economy in itsmanufacture, and thereby obviating the most objectionable features ofall kinds of Satchel-bottom bags as now made. These results are securedby the peculiar construction of the bottom, as hereinafter explained,reference being had to the accompanying drawing, like lettersrepresenting like parts'.

Figure lrepresents a portion of a continuous sheet of paper of which thebags are made, which is divided into sheets of the'desired length at theirregular lines A A, the sheet between the lines A A being of sufficientlength to makev two bags. Fig. 2 `represents the sheet folded intoatube, they edges of which are lapped and secured by paste or itsequivalent, at the longitudinal lines B. llt will be noticed that oneside of each end of the tube projects beyond the other side, this resultbeing accomplished without'any loss of paper. The tube is then dividedat the dotted line B, orthe sheet -maybe thus divided at the dotted lineB, Fig. l, before the tube is made, making two tubes of like shape andsize, each of which is afterward cut longitudinally at the lines C C, tofacilitate the folding of the bottom, andfinconnection with thevprojecting side, as explained, securing to the `bottom its peculiarconstruction, the great advantages of which will hereinafter appear.

Fig. 3 represents the first fold `in forming theA bottom, which is made`by separating the two sides of the end, the side Lbeing held in itsoriginal position, and the shorter side L' being folded back over a thinrigid plate lying dotted line e down-upon the lateral sides F F afterthe application of paste, or its equivalent, as shown in Fig. 4. f

The shorter sideis then folded at the line a! over upon the lateral sideF F, and the lower4 edge ofthe longer side L, as shown in Fig. 5,bringing the upper edge of the shorter side L up to and leven with ahorizontal line drawn through the middle vof the bottom, thereby 4enabling the two sides vof the bottom to be easily folded together, asin Fig. 6, the upper edge of the shorter side L forming the creasingline.

Fig. 7 represents the bag when distended or filled.

'The great advantages of my invention are these: It Will be readily seenthat, by making one side of the end of the tube longer than the other,these* sides can be separated, preparatory to folding the bottom, withmore ease and rapidity than if they were of even length, as is the casein all other satchel-bottom bags, thus largely reducing the expense ofmanufacture.

And', furthermore, when the bottom is made the lap or double thicknessformed by the bringing together of the sides L and L', lies .justoutside of the middle or dividing line of the bottom, and forms acreasing line for the last or finishing fold. And, when the last fold ismade, there being one or more thicknesses of paper less than in otherbags at the point where the crease or fold lies, the tendency ofthebottom to spring back or resume its former shape is entirelyobviated. This tendency heilig so great an obstaclein the manufacture ofSatchel-bottom bags that the greater portion of them are made andconsidered finished, as shown in Fig. 5,-without folding thetwo sides ofthe bottom together, notwithstanding the great objection thereto, towit, the extra thicknesses of paper, caused by the lapping of one-halfof the bottom down upon the side of the bag, almost invariablyinterferes with the printing or branding ot' the bag, making manyimperfect impressions, as well as being veryT destructive to the typesused, and also to the tympan of used without being branded by printing,therrrcE.

gressively shown in Figs. 2, 3, 4, and 5, to form Satchel-bottom bags.
